   co-base.css - SHARED BASE LAYER (loaded on EVERY page, first).
   Single source of truth for: @font-face, :root design tokens, reset/base,
   layout primitives, eyebrow, type scale, buttons, header/nav + mobile nav,
   language switcher, cards, reveal animation, footer (full layout) + cookie
   button, cookie-consent banner, theme toggle, and the dark-mode token remap.
   Extracted verbatim from the home bundle to kill the chrome/token duplication
   that previously drifted between co-home.css and co-system.css. Page-specific
   section styles live in co-home.css (home) + co-system.css/co-pages.css (sub).
   DO NOT re-add chrome/token rules to those files.
